First up, the Royal Navy is called out to assist the Helimed Air Ambulance whose crew is treating a fallen lumberjack with a suspected broken leg on the site of a new wind farm near Abington, in South Lanarkshire. Although the Helimed paramedics are on scene, they do not have the winching capability needed to get the casualty on board and it is impossible to get him out on foot, as they are surrounded by felled trees and heavy woodland. Flying conditions mean that Rescue 177 needs to put winchman Sgt Lee Haggerty out at a height of 120 feet, but as they are using almost all of the aircrafts power to hover, an engine failure would leave no option other than to crash-land on the forest floor below…

Meanwhile, on the island of South Uist, a hill runner is stranded with a serious knee injury on the side of Ben Kenneth. Winchman Simon Price and the crew of Rescue 100 fly 82miles to rescue him, but harsh weather conditions make it dangerous for both the crew and the casualty. Immobilised and wet from a swim at the start of the competition, the casualty has been stranded on the hill and exposed to freezing gusts of wind for over an hour. He is in a potentially fatal hypothermic state and it is crucial that the crew gets him off the hillside as quickly as possible.
